Abstract (en)
An apparatus to indicate unauthorized manipulation of at least one protected device enclosed in a housing is provided. The apparatus includes a structure attached to a first portion of the housing and a token switch attached to a second portion of the housing. The token switch is operably positioned with reference to the structure. The token switch includes a plunger, and a register programmed with a value. The register is communicatively coupled with a processor in a circuit. The circuit is communicatively coupled to drive the device. The structure, the token switch, and the circuit are internal to the housing when the housing is in a closed position. The plunger and the structure are positioned to generate a current when the housing is opened. The programmed value in the register is changed by the generated current and the processor takes an action responsive to the change in the programmed value.
